Account Import with Bill to and Ship to information

Account Import with Bill to and Ship to information

Super basic question, as we are just implementing Zoho CRM.  Does anyone have best practices on how to load Account information from an ERP system based on Bill To and Ship To numbers?  We are having difficulty with the Account/Parent relationship and the fact that our ERP system uses the same name for most Bill To and Ship To accounts all with the same numbers.  All of the Ship To numbers have different addresses as well. 

Here is an example of the data:
Bill To            Ship To
Account Name
169301 169301
Company 1
169301 169302
Company 1
169301 169303
Company 1

Any help is appreciated.

Thanks!
